An external pull-down resistor is required for the FLTA1 pin on PIC24FJ16MC101 (20-pin) devices.
The FLTB1 pin is available in PIC24FJ(16/32)MC102/104 devices only.
The PWM Fault pins are enabled during any reset event. Refer to Section 15.2 “PWM Faults” for more
information on the PWM faults.
This pin is available in PIC24FJ(16/32)MC104 devices only.
Not all pins are available on all devices. Refer to the specific device in the “Pin Diagrams” section for
availability.
